However, in windy weather, the windproof components are difficult to adjust, and the protective shed is prone to deformation and collapse, leading to poor windproof performance, structural damage, and safety hazards. Therefore, a support-free inflatable temporary protective shed for watermelon cultivation is provided. Utility Model Content

[0004] The main purpose of this utility model is to provide a supportless inflatable temporary protective shed for watermelon cultivation, in order to solve the problems mentioned in related technologies, such as the difficulty in adjusting windproof components in windy weather and the easy deformation and collapse of the protective shed, which lead to poor windproof effect, structural damage to the protective shed, and safety hazards.

[0005] To achieve the above objectives, according to one aspect of the present invention, a supportless inflatable temporary protective shed for watermelon cultivation is provided, comprising a protective shed, wherein fixed plates are fixedly installed on both sides of the bottom of the protective shed, the protective shed includes at least an airbag frame, the airbag frame includes at least a plurality of first airbags arranged longitudinally and a plurality of second airbags arranged laterally, and the first airbags and second airbags are arranged alternately and connected, protective layers are fixedly connected to both the inner and outer sides of the airbag frame, and the protective shed is also provided with windproof components to prevent it from being deformed by wind, and the four corner edges of the windproof components are connected to the fixed plates.

[0006] Furthermore, the second airbag is inverted U-shaped, and each second airbag is fixedly connected with a support rib, and a connecting layer is fixedly connected between two adjacent second airbags.

[0029] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0030] Please see Figures 1-9As shown, the purpose of this embodiment is to provide a supportless inflatable temporary protective shed for watermelon cultivation, including a protective shed 1. The protective shed 1 has fixed plates 2 fixedly installed on both sides of its bottom. The protective shed 1 includes at least an airbag frame 11. The airbag frame 11 includes at least a plurality of first airbags 111 arranged longitudinally and a plurality of second airbags 112 arranged laterally. The first airbags 111 and the second airbags 112 are arranged alternately and connected. The inner and outer sides of the airbag frame 11 are fixedly connected with protective layers. The protective shed 1 is also provided with windproof components 3 to prevent it from being deformed by the wind. The four corner edges of the windproof components 3 are connected to the fixed plates 2.

[0031] The staggered arrangement of the first airbag 111 and the second airbag 112 greatly enhances the overall stability of the airbag frame 11. The first airbag 111 is arranged longitudinally, like the spine of the frame, providing the main support direction for the entire structure, while the second airbag 112 is arranged laterally. The second airbag 112 is inverted U-shaped. This shape not only increases the contact area between the airbag and the ground or top cover, but also disperses the pressure from the outside through its arc structure, making the frame more stable.

[0032] The inflation port is located at the center of the first airbag 111, facilitating rapid and uniform inflation. When gas enters the first airbag 111 through the inflation port, it rapidly diffuses along the airbag's channels. Since the first airbag 111 and the second airbag 112 are interconnected, the gas can flow smoothly into the second airbag 112, ensuring uniform expansion of the entire frame. Each second airbag 112 is fixedly connected with a support rib 113. The support rib 113 plays a supporting and shaping role when the airbag is inflated, supporting the second airbag 112 like a skeleton, preventing it from deforming or collapsing due to internal pressure during inflation. At the same time, the support rib 113 also enhances the wind pressure resistance of the airbag frame 11, allowing the protective shed 1 to remain stable even in severe weather. Furthermore, a connecting layer 114 is fixedly connected between two adjacent second airbags 112, further enhancing the connection stability of the airbag frame 11, ensuring a tight connection between each airbag, and preventing structural instability caused by gaps or loosening between airbags.

[0033] The protective layer includes heat insulation layers 12 set on both sides of the airbag frame 11, which can effectively prevent external heat from being transferred into the greenhouse and reduce heat loss inside the greenhouse. This two-way heat preservation effect allows the protective greenhouse 1 to maintain a relatively stable temperature environment even in areas with large day-night temperature differences, which is conducive to the stable growth and development of watermelons. The airbag frame 11 and the heat insulation layer 12 are filled with heat insulation material, which can further enhance the heat preservation effect and structural strength of the protective greenhouse 1, and the heat insulation material is preferably glass wool.

[0034] The windproof component 3 includes at least a mesh cover 31, which has a certain degree of elasticity. The mesh cover 31 is in close contact with the upper surface of the outer heat insulation layer 12, and can effectively prevent the protective shed 1 from being blown off course or deformed by the wind due to its inflation design, even in severe weather such as strong winds. In order to adapt to the height changes of the protective shed 1 under different inflation capacities, an adjustment rod 32 is connected to each of the four corner edges of the mesh cover 31. The adjustment rod 32 can adjust the height, and a flexible photovoltaic film 33 is fixedly connected to the top center of the mesh cover 31. This flexible photovoltaic film 33 not only has the function of windproofing, but also converts solar energy into electrical energy to provide power support for lighting, ventilation or other equipment inside the protective shed 1.

[0035] The adjusting rod 32 includes a fixed cylinder 321 fixedly installed on the fixed plate 2. A connecting rod 322 is threadedly installed on the fixed cylinder 321. A connecting rope 323 is provided at one end of the connecting rod 322. The connecting rope 323 is fixedly connected to the mesh cover 31. One end of the connecting rope 323 is fixedly connected to the connecting rod 322, and the other end is tightly tied to the four corner edges of the mesh cover 31. When it is necessary to adjust the height of the mesh cover 31 so that it is in close contact with the upper surface of the outer heat insulation layer 12, the connecting rod 322 is rotated to adjust the length of its protruding end in the fixed cylinder 321. A nut for fixing is also threaded on the connecting rod 322.

[0036] The fixing plate 2 has several magnetic grooves, and weight-adding blocks 22 are magnetically attached to the magnetic grooves. The weight-adding blocks 22 are preferably steel blocks. The weight-adding blocks 22 are installed as needed. The magnetic design allows the weight-adding blocks 22 to be easily attached to the magnetic grooves without the need for additional fasteners or tools. This enhances the stability and accuracy of the installation. According to actual needs, users can choose to install different numbers or weights of weight-adding blocks 22 to adjust the load-bearing capacity and stability of the fixing plate 2. Several ground anchors 21 are fixedly connected to the bottom of the fixing plate 2. By anchoring one end of the ground anchor 21 to the soil, the position of the fixing plate 2 is fixed, thereby fixing the installation position of the protective shed 1.

[0037] The protective shed 1 has several ventilation windows 14 symmetrically arranged on both sides, providing necessary air circulation channels inside the shed. The protective shed 1 also has several guide plates 4 symmetrically arranged on both sides, with the guide plates 4 located above the ventilation windows 14. The guide plates 4 have an arc-shaped structure that curves from the middle to the lower ends on both sides. When rainwater falls on the arc-shaped surface of the outer insulation layer 12, due to the action of gravity and surface tension, the rainwater will flow along the curved surface of the outer insulation layer 12. Without the presence of the guide plates 4, the rainwater may flow directly to the ventilation windows 14 and then seep into the shed, causing damage to the watermelon seedlings and personnel. However, the arc-shaped structure of the guide plates 4 cleverly changes the flow path of the rainwater. When the rainwater flows onto the guide plates 4, due to their design that curves to the lower ends on both sides, the rainwater will be guided to both sides, away from the ventilation windows 14, effectively protecting the safety of the watermelon seedlings and personnel inside the shed.

[0038] In practical use, when the protective shed 1 needs to be used temporarily, a suitable installation location is selected, the fixing plate 2 is placed in the selected position, and it is anchored in the soil using the ground anchor 21. As needed, weight-adding blocks 22 are installed in the magnetic grooves of the fixing plate 2. An inflation device is connected to the inflation port in the middle of the airbag frame 11, and inflation begins. Gas enters the first airbag 111 through the inflation port and then flows smoothly into the interconnected second airbags 112, ensuring uniform expansion of the entire frame. During inflation, the supporting ribs 113 provide support and shape retention, preventing the airbags from deforming or... After the collapse and inflation are completed, adjust the adjusting rod 32 according to the height of the protective shed 1 so that the net cover 31 is in close contact with the upper surface of the outer heat insulation layer 12. That is, rotate the connecting rod 322 to adjust the length of its protruding end in the fixing cylinder 321 and fix it with a nut. When it is necessary to move or disassemble the protective shed 1, first deflate the airbag frame 11 to collapse, disassemble the windproof component 3, remove the weight block 22, and pull out the ground anchor 21. Store the fixing plate 2 together with other components of the protective shed 1. In rainy weather, the deflector plate 4 will effectively guide rainwater away from the ventilation window 14 to prevent rainwater from seeping into the shed.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
